Mounted upon the frame 35 and insulated therefrom a plurality of brushes corresponding in riul 88 i ting rod number to the number of tablets provided and I designated 91, 92, 93, 91, and 96 arranged to contact in the oll normal positions of the tablets with the contact plate 88 of the tablets 83, 8 1, and 86 respectively These brushes are connected to conductors 101, 102, 103, 101 105 and 106 respectively.

The organ control box 18 consists of a plurality of tablets such as the tablets 110, 111 and 112 loosely mounted upon at rod 113, supported in the framework The tablets and 111 are provided on their un er surfaces wilh sheets of conducting um H11 115 and 116 rwupectivcly, which make conta with the rod 113, and which at suitable times coop irate with the brushes 111 118,119 and 121'). To the tablet 1? secured a, small semi-circular piece it insulating material 125 into which is a segment of co'ndmtino material l in serl'c d 126, whi 127 to l (o-operating will! insulaliih mater al 1'35 and the segment are lhree nrusl 122% 129 and 13) which secured to the irameworh 35. 117 and 118 are connected to COI'HlUCl'Olrj and 136 respectively; the brushes 119 and 120 the 152 3 are connected to conductors 137 and 138 re spectively and the brushes 128', 129 and 130 are connected to conductors 139, 1 1-0 and 111 respectively, the conductor 14:1 joining the conductor 139. A brush 115 is provided which engages the rod 113, and to which is connected a conductor 1 16, the other end which is connected to the conductor 1-9.

h is ehwtrically connected by a brush 'lhe brushes 219 of ti lrznnoworl ere pivoted links 158 and to the other ends of which are pivoted levers and 156 which are provided with handles 15'? and 158. T he 155 and 156 are loosely mounted upon 159 wnich are supported in the frame- 'k The. members 150 and 151 are provided with segments of conducting material 164 and (lo-operating with the members 150 are four brushes 16-6, 197 168 and 169, and co-operating with the inen'ibers 151 are four brushes 171, 172, 173 and 17 1.. These, brushes are supported by parts of the framework 35. The brushes 166 16, 168 and 169 of the group selector ere connected conductors 181, 182 and 183 i pectively, and the brushes 111, 172, 1'78 and 11'4- of the group selector ected to conductors 185, 186 18? an 7 oectively.
